Just looking at the web stats for 2009 against 2008
MAR08 Total posts: 1,770 New topics: 112 most users online: 93
MAR09 Total posts: 965 New topics: 51 Most users online: 35
Down quite a bit isn't it 
Si
Well the Posts and New topics are relevant but I actually doubt the use of comparing "Most users" on line. Unfortunately search engines crawling the site count as users. Given the new server is much faster than the old one the search engines will be in and out much faster. So it may appear that there are fewer visitors.
New members is perhaps more interesting. March last year we had 22 new members compared with 11 this year.
However, if we look at the first Quarter. Last year we had 72 new members this year 88 new members have joined.
Also if you look a page views in March 2008 it was 213207 this year it was 326684.
Ahhh... Statistics! there great you can make them say what ever you want. :-)
Also as time goes by we build up a larger bank of information so may newcomers don't have the need to ask so many questions so not so many replies.
